Age spots and freckles usually clear with pigment laser; melasma can darken with the same settings. Dr Sin Yong explains how they are told apart and where each one is treated.
WhatsApp to Enquire →Key facts ↓Age spots are sharply edged brown spots from years of sun that stay the same all year. Freckles are small spots from childhood that darken with sun and fade without it. Melasma is a symmetrical patch with blurred edges, driven by hormones, light and heat. Age spots and freckles usually clear with pigment laser; melasma is managed with sun protection, topical care and gentle toning.
Age spots, freckles and melasma are the three most common reasons people in Singapore ask about pigmentation. They can look alike, they often appear on the same face, and they respond differently to treatment. Age spots and freckles usually clear well with a pigment laser used spot by spot. Melasma can turn darker after the same settings, because it is driven by hormones, light and heat and involves the deeper skin.
This page is a decision guide. It sets out how the three are told apart, what each one means for treatment, and where to go next. It is not a substitute for an examination: the diagnosis is made in person, under good light and magnification, and some spots need a closer look. Each condition has its own treatment page: age spot removal, freckles removal and melasma treatment.
| Age spots (sun spots, solar lentigines) | Freckles (ephelides) | Melasma | |
|---|---|---|---|
| Usually starts | From the thirties onwards, after years of sun | Childhood | Adulthood, often in women after pregnancy or hormonal change |
| Size and number | Few to several, a few millimetres to over a centimetre | Many, small, a few millimetres | Patches, often several centimetres |
| Edges | Sharp; you can trace them | Fairly sharp | Blurred; blends into normal skin |
| Colour | Light to dark brown | Light to mid brown | Brown or grey-brown |
| Pattern | Cheeks, temples, backs of hands, forearms | Nose, cheeks, shoulders | Symmetrical: cheeks, forehead, upper lip, jaw |
| With less sun | Stay the same | Fade | Lighten slowly |
| What drives it | Cumulative UV | Inherited response to UV | Hormones, UV and visible light, heat, deeper skin changes |
| Depth | Surface (epidermis) | Surface (epidermis) | Surface and deeper (dermis), often mixed |
| Laser response | Good, often 1–3 sessions | Good; returns with sun | Cautious; strong settings can darken it |
| Long term | New spots can form with sun | Return with sun | Chronic; tends to recur; managed, not cured |
Two simpler clues help. An age spot has an edge you can trace with a fingertip and stays the same all year. Melasma is a patch with no clear edge that mirrors itself on both sides of the face. Freckles are small and many, and were there in childhood.
These questions point towards one or another, but only an examination confirms it.
| Question | If yes, it points towards |
|---|---|
| Did the spots first appear in childhood or the teens? | Freckles |
| Do they fade noticeably after time away from the sun? | Freckles (melasma lightens more slowly) |
| Are they larger, darker spots with sharp edges, which appeared in adulthood? | Age spots |
| Are they on the backs of your hands as well as your face? | Age spots |
| Is it a patch with blurred edges, matching on both cheeks? | Melasma |
| Did it start or worsen during pregnancy or with hormonal medicine? | Melasma |
| Does it get darker after heat, such as cooking, hot yoga or saunas? | Melasma |
| Are there blue-grey speckles on the upper cheeks? | Hori’s naevus, a deeper pigment |
| Did the mark appear where a pimple or rash was? | Post-inflammatory pigmentation |
Age spots are treated spot by spot with a picosecond or Q-switched pigment laser, often at 532 nm for surface pigment, on the DEKA TORO or Fotona StarWalker PQX. Many clear in one to three sessions, with darkening and fine crusts for about a week. A spot that has become rough or raised is often a seborrhoeic keratosis and is treated differently. See age spot removal in Singapore and the condition page sun spots and age spots.
Freckles respond to the same kind of spot treatment and often lighten markedly in one to three sessions, but because the tendency is inherited, they return with sun. Sun protection decides how long the result lasts. See freckles removal in Singapore and freckles: causes and signs.
Melasma is managed rather than cured. The base is daily protection from UV, visible light and heat; topical treatment and, for suitable people, a prescription medicine reduce pigment production; and gentle, low-energy laser toning is added cautiously as support. Strong spot settings are avoided because they can darken it. See melasma treatment in Singapore and melasma: causes, types and triggers.
A common face in Singapore has freckles on the nose, an age spot or two on the temple and early melasma on the cheeks. The plan then treats them separately in one programme: spot settings for the defined spots, gentle toning and topical care for the melasma, and sun protection for all three. The wider guide is pigmentation treatment in Singapore.
“Three brown marks can look alike in a mirror and need three different plans. Treating melasma as a sun spot is how a small problem becomes a larger one.”
| Mistake | What can happen |
|---|---|
| Melasma treated with strong spot settings | Darker patches (post-inflammatory or rebound pigmentation) that take months to settle |
| Hori’s naevus treated as melasma | Little change after many gentle sessions, because the pigment is deeper |
| Seborrhoeic keratosis treated as an age spot | Partial lightening; the raised spot remains |
| A changing mole or early skin cancer lasered as a sun spot | Delayed diagnosis, because the pigment that would show what it was is removed |
| Freckles treated without a sun plan | Clear skin for a season, then freckles back |
Laser for pigment is safe and effective when it is matched to the right diagnosis. In a randomised split-face study of age spots in Asian patients, picosecond laser cleared pigment with fewer cases of darkening than Q-switched laser; in melasma, by contrast, added laser helped during treatment but the difference faded at follow-up. The same device behaves differently on different pigment.
General clinical observations used at consultation; they describe what is checked, not any individual result.
Most brown spots are harmless. These features mean a spot should be examined, and sometimes biopsied, before any cosmetic treatment.
These are referred for assessment first. Moles are covered in mole removal.
The common thread is light. Age spots come from cumulative UV, freckles from an inherited response to UV, and melasma from UV, visible light and heat on hormonally sensitive skin. Daily broad-spectrum sunscreen, reapplied outdoors, is the base for all three; for melasma, a tinted sunscreen that also blocks visible light helps further. A hat, shade at midday and care on holiday add more than any single product. In Singapore, UV is strong all year, so protection is daily rather than seasonal. The consultation fee at IN Eternity Clinic is S$120, waived with any medical treatment.
Age spots have sharp edges you can trace, stay the same all year and often appear on the backs of the hands too. Melasma is a patch with blurred edges, usually matching on both cheeks, forehead or upper lip, and is linked to hormones, light and heat. An examination confirms it.
No. Freckles appear in childhood, are small and many, and fade with less sun. Age spots appear in adulthood after years of sun, are larger and sharply edged, and do not fade. Both respond to pigment laser.
Pico laser can support melasma treatment at gentle settings, alongside sun protection and topical care. Strong spot settings can darken melasma. In studies, added laser helped during treatment but the benefit faded without maintenance.
Melasma, because it is chronic, involves the deeper skin and responds to hormones, light and heat. It is managed over time rather than cleared. Freckles and age spots usually respond within a few sessions.
Yes, and it is common. The plan treats them separately: spot settings for freckles, gentle toning and topical care for melasma, and sun protection for both.
Age spots themselves are harmless. They show the skin has had a lot of sun, which also raises skin cancer risk. A spot that is irregular, changing, bleeding or different from the others should be examined before any treatment.
Common reasons are post-inflammatory darkening after treatment, melasma that was treated with strong settings, or sun exposure soon after. The cause is assessed, laser is paused and the skin is settled with sun protection and topical care.
Hori’s naevus is a deeper, grey-brown or blue-grey speckled pigment on the upper cheeks, common in East Asian women and often mistaken for melasma. It needs longer laser wavelengths and several sessions, and does not respond to melasma creams.
